Influence of Casting Technique on the mechanical properties of bimetal composites

摘要：

According to the characteristic of two liquid and bimetal composite interface, the influence of the casting techniques on the interface microstructure, wear and comprehensive properties were researched by using scanning electron microscope (SEM) and energy dispersive X-ray analysis(EDAX). The results show that the casting technique has an effect on the surface quality and the stress state of the composites, but also has great effect on the interface microstructure, morphology and constitute phase. In this paper, a special casting technology was used to prepare the bimetal composites. No two-metal mixture layer was observed at the interface. On the contrary, a metallurgy interface was found, which provides high working security. A product rate of 95％ was achieved by this special casting process.The service life is 50％ higher than that of the commercial products.
